Zusammenfassung:	A green paper is provided for producing a gas diffusion layer (GDL) for a fuel cell. A process is for producing a green paper for producing a gas diffusion layer (GDL) for a fuel cell. The green paper includes at least one first, watermarked paper web. The watermark forms the patterning for the flow field or gas distribution structure of the gas diffusion layer (GDL) produced from the green paper. The first paper web is admixed with metal powder and/or metal fibres. The eventual GDL is formed after debindering, sintering, coating, deposition of atomic layers (ALD-atomic layer deposition) and further operating steps.
